Have you got the default app exe on your system? It used to come with the tutorial but the author asked us to link his site instead and since then his site has shut down and as a result we haven't got a copy of the defaultapp.exe which is what you need to make that process work correctly...
Perhaps try http://www.flashkit.com
as they have the same tutorial (from memory).
Please don't email or PM
me Flash questions, that's what the Forums are for!
Please don't rely on me reading my PMs either. Email me about important stuff.
